Confusing pending sleep message after Lock Device (reboot)

Originally, Lock Device would reboot and sleep. Now, it reboots and stays on (asks for the pin).

Sometimes when entering my pin right after a "Lock Device (reboot)", I get a message "Uninterruptible operation pending. Please retry the sleep request in a couple seconds." Once I dismiss it, the system proceeds with mounting PDDB. It's a bit confusing to the user because the user didn't not just request sleep. Furthermore the user may not be aware that Lock Device defers a sleep request for historical reasons.

To improve UX and prevent that message, should we remove the line scheduling that deferred sleep after reboot? It's here: https://github.com/betrusted-io/xous-core/blob/dev/services/status/src/main.rs#L1295

Note that the message never appears after a cold start (Shutdown then plug in). The unexpected behavior occurs only after a Lock Device (reboot), then log in.
